Question

At a party, the cheese pizza is cut into 9 slices and the veggie pizza is cut into 12 slices. If the host wants to serve identical platters that contain the same combination of cheese and veggie slices, with no slices left over, what is the greatest number of platters the host can prepare?

Answer 1

Answer: 36 or 72

Explanation:

I chose 36 because both 9 and 12 go into 36, If the host wanted more than 36 slices, 72 would be another number that would have no left overs.

Answer 2

3 platters

Explanation:

You need to find a factor of both 9 and 12. The only common factors are 1 and 3. Then, you pick the largest, which is 3 in this instance. Then, you can figure out how many pieces of each would be on a platter. 9/3=3, so there will be 3 slices of cheese on a platter, and 12/3=4, so there will be 4 veggie pizza slices on each platter.
